Connecting mechanism for natural gas sampling

Abstract

The invention provides a connecting mechanism for natural gas sampling, and the connecting mechanism for natural gas sampling is used for connecting a gas production pipeline with a sampling pipe. Theconnecting mechanism for natural gas sampling comprises an upper pipe clamp attached to the top of the gas production pipeline, a lower pipe clamp opposite to the upper pipe clamp and attached to thebottom of the gas production pipeline, bolts and connecting rods, one ends of the connecting rods are connected with the middles of the bolts, and the other ends of the connecting rods are connectedwith the sampling pipe; the two bolts and the two connecting rods are arranged symmetrically, one end of each bolt is rotatably connected with one end of the lower pipe clamp, and the other end of each bolt can be connected with one end of the upper pipe clamp in a clamped mode and locked on the upper pipe clamp through nuts. According to the connecting mechanism for natural gas sampling, the upper pipe clamp and the lower pipe clamp can be quickly connected to the gas production pipeline through the bolts rotationally connected with the lower pipe clamp, a connecting fulcrum is provided for butt joint of the sampling pipe and a sampling opening of the gas production pipeline, during disassembly, the upper pipe clamp and the lower pipe clamp can be disconnected by reversely rotating the bolts to be separated from the upper pipe clamp after the nuts are loosened, so that the upper pipe clamp and the lower pipe clamp can be quickly taken down, operation is convenient and simple, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for natural gas exploitation, in particular to a connection mechanism for natural gas sampling. Background technique [0002] Natural gas is a gaseous fossil fuel mainly composed of methane. It mainly exists in oil fields and natural gas fields, and a small amount comes out of coal seams. The main purpose of natural gas is as fuel, which can produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Natural gas is mainly composed of gaseous low molecular weight hydrocarbons and non-hydrocarbon gases. [0003] During the extraction of natural gas, in order to understand the composition and purity of natural gas, sampling ports are generally set up on the pipeline to sample and test the natural gas at the extraction site, which requires a sampling device. However, the disassembly and assemb...

Problems solved by technology

[0004]Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a connection mechanism for natural gas sampling, to solve the cumbersome disassembly and assembly operation of the existing connection mechanism, and the connection is not enough Stable and firm, the sealing performance between the sampling port and the sampling tube is poor, which leads to the problem that the sampling tube is easy to fall off and cause leakage
